Like the title says, Syncthing has been on “Preparing to Sync” for almost 2 days now. The folder structure is being created, but no files have moved over. Out of 93,000 folders about 35,000 have been created in that time.
I don’t think it’s frozen but it’s definitely going really slow.
Is it normal that Synching would create the full folder structure first before syncing any files? And is it normal for it to take this long with that amount of data?
Total number if files is 782,608 totaling ~2.48TB
The setup is a little odd so I’ll explain the details below:
Client 1: (current source of all files)
- Synology DS918+, 16GB Ram, 5Gb/s NIC
- This end of Syncthing is fully indexed and ready to go.
- I have verified all permissions are correct.
- The sync target is a bind mount of the user home folders (There is a reason I did it this way).
- Structure is /volume1/ST-Bind/homes/{username}
- homes is the sync target so the synching files don’t get written into the users home folder.
Client 2: (Current Destination of all files)
- Unraid, Ryzen 5 2600+, 64GB DDR4, 10Gb/s NIC.
- Syncthing Docker.
- Verified permissions in the container match the destination folder.
- The structure is very similar. with /homes/{user}. Homes is a “real” Dir and is the sync target to that the syncthing files are written there instead of the user folder.
- The User folders on this end are RClone mounts.
- The Rclone mounts are connected to my Seafile server, as this is the only way to expose Seafile as a R/W directory outside of using its own apps.
- The Seafile storage is located on a 24TB ZFS pool of 3 groups of 2 mirror devices each.
- The Rclone vfs_cache is located on a mirror ZFS pool of 2 nvme 2TB SSDs and is a full read & write cache.
- The Syncthing container, the homes dir and the Rclone mount all have the same permissions.
- The RClone mount started as empty when setting up syncthing.
Im not seeing any errors in the logs, I haven’t noticed any permission errors, and I have seen no notifications within Syncthing. Unless I’m just not enabling the correct “Debugging Facilities”.
The Syncthing files were created properly in the /homes directories on both sides. And empty directories are slowing being created through the RClone Mount and are visible in Seafile.
My only concern is that after almost 2 days only ~35,000 directories have been created out of ~93,000 and zero files have been synced yet, however more and more directories are slowly but steadily still being created. Is this normal or is something wrong?
